Business 40 Improvement Project

As Winston-Salem's downtown continues to be a thriving urban hub, the 1.2-mile stretch of Business 40 that runs through downtown is underway for structural improvements and overall beautification. The three-year project, spearheaded by the North Carolina Department of Transportation (NCDOT), is a multi-phased project is slated for completion Spring 2020. The finished project will offer travelers safer roadways in and out of Winston-Salem's bustling downtown, and add and improve pedestrian walkways through and around downtown.

Latest News:

  • Lane Closures January 23 - 24, 2020

    Location # 1:  Beginning at 9 p.m. Thursday, Jan. 23, crews will close the inside lane of eastbound and westbound Business 40 between Cloverdale Avenue and Peters Creek Parkway.
    Then at 11 p.m., both lanes of EASTBOUND Business 40 will be closed and eastbound traffic will be directed onto the Cloverdale Avenue exit. Motorists can follow the signed detour of Cloverdale Avenue, W. 1st Street, and Peters Creek Parkway to move around the closed portion. The purpose of the closure is for crews to install an overhead sign structure near the Peters Creek Parkway bridge and the crane required to lift the structure will take up both lanes of eastbound Business 40.
    The work will be complete prior to 6 a.m. Friday, Jan. 24 and all lanes will be reopened at that time.

    For a map of the closure location, please click the following link: Nighttime Closure of Eastbound Business 40 near Cloverdale Avenue 

    Location # 2:  Beginning at 2 a.m., Friday morning January 24, crews will be closing the ramp from Main Street to eastbound Business 40. The closure is necessary to remove the concrete barrier that is currently in place along the ramp.
    The work will be completed and the ramp reopened by 6 a.m., Friday morning.  
  • Liberty Street bridge is now open!
     
  • As of August 1, Business 40 construction crews are closing the intersection of High Street and Brookstown Avenue in downtown Winston-Salem, extending the Brookstown Avenue closure to include the Brookstown Avenue / High Street intersection. With High Street being a one-way traffic pattern, closing the intersection prevents access to the parking lot of the Shaffner House/Flour Box Tea Room and Cafe. To provide access, the portion of High Street between Marshall Street and the parking lot has been temporarily changed to a two-way pattern.  Motorists traveling north on Marshall Street can turn left onto High Street and access the parking lot.
